Title: Screen for carrying fine particles
Inventor: OMURA HIROSHI
IPC: G03G15/08
Filed: 1987-04-30
Abstract: PURPOSE:To obtain a member appropriate for carrying fine particles by the attractive force of electrons charged on the surface of a screen by sticking metal oxide to the surface of the screen consisting of a conductor to adjust the surface resistance of the screen. CONSTITUTION:In an electronic printer or other equipments utilizing toner 3, metal oxide is stuck to the surface of a thin plate such as the screen 9 consisting of a conductor to adjust its surface resistance. The screen 9 to be used for carrying fine particles such as toner with uniform thickness is usually constituted of a conductor, and if the surface resistance is too small, electrified charge is leaked. When the surface resistance is too large, sufficient charge can not be supplied from a power supply to the surface of the screen 9 and the toner can not be stuck to the surface of the screen 9. Consequently, the member is appropriate for carrying fine particles with uniform thickness in addition to application to a toner carrying device.

Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent the entrainment of an upper paper sheet and improve a stacking property by setting the friction coefficient of at least one of outside drive rollers lower than the friction coefficient of drive rollers at the center section. SOLUTION: The friction coefficient of outside drive rollers 66a, 66d is set lower than the friction coefficient of inside drive rollers 66b, 66c, i.e., materials are selected so that the friction coefficients of the drive rollers 66a-66d have relations 66a≈66d, 66b≈66c, 66a<66b. Practically, for rubber rollers of the same kind, the rubber hardness of the inside drive rollers 66b, 66c is made higher than the rubber hardness of the outside drive rollers 66a, 66d, thus the friction coefficient of the outside drive rollers 66a, 66d is set lower. Even when the end sections of paper bundles P on the side of staples 20 are brought into contact with the outside drive roller 66a, for example, no entrainment (biased returning effect) occurs, and a defective stack such as a rotating stack can be prevented.

Title: Icemaker for refrigerator
Inventor: NITTA YOICHI
IPC: F25C1/24
Filed: 1991-04-10
Abstract: PURPOSE:To prevent freezing of an icemaker due to insufficient supply of water by detecting temperatures before start of supply of water at the end of a feed water tube for intermittently supplying a predetermined amount of water to an icemaking tray and after lapse of a predetermined time from the start, and sensing presence or absence of storage water in a feed water tank according to its temperature difference. CONSTITUTION:After a predetermined time from when an operation of icemaking is started, a temperature of a feed water tube is detected by a temperature sensor A, and stored in a controller microcomputer. A feed water pump 6 is driven at the temperature of the tube lower than that of water of a feed water tank 5 to pour water in an icemaking tray 1. The sensor A detects a water temperature of the tank 5, compares it with the stored temperature of the tube after lapse of a time, confirms that there is water in the tank 5 in a state that the temperature of the tube exceeds 5 deg.C, judges that there is no water in the tank 5 at 5 deg.C or lower, and fires a feed water alarm. When it is confirmed that an icemaking tray temperature sensor B senses an icemaking temperature or lower, the tray 1 is rotated to drop ice in a stocker 3. Thus, the presence or absence of water in the tank can be effectively sensed.

Title: Muting circuit of fm receiver
Inventor: SHIBATA JIYUNICHI
IPC: H04B1/10
Filed: 1978-08-29
Abstract: PURPOSE:To reduce noises without letting a listener feel a physical disorder due to muting by making a signal attenuation value in muting operation correspond to a demodulation level right before an electric field becomes slight. CONSTITUTION:Intermediate frequency signal A is inputted to direct-current voltage generating circuit 1 via capacitor C1. On detecting the level of signal A, circuit 1 applies inversion output D of a direct-current voltage in proportion to signal A to voltage control attenuator VCA3. Demodulated signal B, on the other hand, is inputted to voltage control attenuator 3 via capacitor C2. The output of VCA3 is led out via capacitor C3 and also inputted to direct-current voltage generating circuit 4. Circuit 4 applies VCA3 with direct-current voltage E in proportion to the input level. In inverse proportion to a difference between signals D and E, VCA3 increases in attenuation value; when the level of signal B is large, the attenuation value is small and when small, it is large, so that demodulated signal F will be outputted.
